摘要： A manipulation device (14) for a microinvasive medical instrument (10) comprises a first grip member (22) and a second grip member (40), that are movable relative to each other, an irrigation port (90) for receiving an irrigation liquid for cleaning the manipulation device (14) between two uses, and an irrigation channel (92, 94, 96, 98) that connects the irrigation port (90) to one or more outlets (93, 95, 33, 65). The irrigation channel (92, 94, 96, 98) is arranged in the first grip member (22).

摘要： The invention relates to a medical instrument having an elongated shaft, a movable tool at a distal end of the shaft, a handle with a movable grip part at a proximal end of the shaft, and a force transmission element which can be moved in the longitudinal direction of the instrument and is operatively connected to the movable grip part and to the tool such that an actuation of the movable grip part is converted into a movement of the tool. The instrument has a spring assembly that is arranged on the handle and has at least one leg spring, which has at least one winding and two legs, and a pin, wherein the at least one winding extends about the pin. When the movable grip part is actuated, a force is applied to at least one of the legs of the leg spring, said force reducing the friction between the winding and the pin such that the leg spring can be rotated about the pin and the force transmission element and the tool can be moved. When a force is transmitted from the tool to the force transmission element in the longitudinal direction thereof, the leg spring cannot be rotated about the pin such that the force transmission element and the tool cannot be moved.

摘要： One embodiment relates to a medical instrument (1) with a hollow shaft (2), an actuating unit (4) arranged at the proximal end (3) of the shaft (2) and an instrument tip (6) with an instrument (7) arranged at the distal end (5) of the shaft (2), wherein the instrument (7) can be actuated via an actuating element (8) which is mounted in the shaft (2) in an axially displaceable manner, and wherein the actuating element (8) is operatively connected to the actuating unit (4) on the proximal side, and wherein the instrument tip (6) can be pivoted relative to the longitudinal axis (10) of the shaft (2) via a joint mechanism (9). According to one embodiment, the instrument tip (6) can be rotated endlessly, wherein a fixing device is provided on the instrument tip (6) with which the loose end (17, 23) of a sewing material (18, 24) can be fixed on the instrument tip (6).

摘要： The present disclosure provides a steering gear for a surgical instrument and the surgical instrument. The steering gear includes two drives for the spatial alignment of a wobble plate rotatively coupled to a main shaft rotatable about a gimbal. The steering gear includes two linear slides each displaceably arranged along a guide axis connected to the two drives. Each linear slide is operatively connected to the wobble plate by an engagement element pair having an engagement opening and a lever element having a rod portion, and a head portion. One of the engagement elements is present on a circumference of the wobble plate and the other engagement element of the engagement element pair is present on a surface portion of the respective linear slide facing the wobble plate, said surface portion being a surface portion on a longitudinal side of the linear slide parallel to the guide axis.
